The Zend_Service_Rackspace is a class that provides a simple API to manage the Rackspace services Cloud Files and Cloud Servers. The load balancers service of Rackspace is not implemented yet. We are planning to release it in the next future. Before you can get started with Zend_Service_Rackspace, you must first register for an account. Please see the Cloud services page on the Rackspace website for more information. After registering, you can get the Username and the API Key from the Rackspace management console under the menu "Your Account" > "API Access". These informations are required to use the Zend_Service_Rackspace classes. The Cloud Files is a service to store any files in a cloud environment. A user can store an unlimited quantity of files and each file can be as large as 5 gigabytes. The files can be private or public. The private files can be accessed using the API of Rackspace. The public files are accessed using a CDN (Content Delivery Network). Rackspace exposes a REST API to manage the Cloud Files. Zend_Service_Rackspace_Files provides the following functionality: Upload files programmatically for tight integration with your application Enable Cloud Files CDN integration on any container for public distribution Create Containers programmatically Retrieve lists of containers and files Rackspace Cloud Servers is a compute service that provides server capacity in the cloud. Cloud Servers come in different flavors of memory, disk space, and CPU. Zend_Service_Rackspace_Servers provides the following functionality: Create/delete new servers List and get information on each server Manage the public/private IP addresses of a server Resize the server capacity Reboot a server Create new images for a server Manage the backup of a server Create a group of server to share the IP addresses for High Availability architecture Eeach service class (Files, Servers) of Rackspace extends the Zend_Service_Rackspace abstract class.
